Refined physical parameters for Chariklo's body and rings from stellar occultations observed between 2013 and 2020
B. E. Morgado, B. Sicardy, F. Braga-Ribas +78
The Centaur (10199) Chariklo has the first rings system discovered around a small object. It was first observed using stellar occultation in 2013. Stellar occultations allow the de…
A posteriori superlinear convergence bounds for block conjugate gradient
Christian E. Schaerer, Daniel B. Szyld, Pedro J. Torres
In this paper, we extend to the block case, the a posteriori bound showing superlinear convergence of Conjugate Gradients developed in [J. Comput. Applied Math., 48 (1993), pp. 327…
Periodic solutions for the Lorentz force equation with singular potentials
Manuel Garzón, Pedro J. Torres
We provide sufficient conditions for the existence of periodic solutions of the of the Lorentz force equation, which models the motion of a charged particle under the action of an…
Periodic bouncing solutions of the Lazer-Solimini equation with weak repulsive singularity
David Rojas, Pedro J. Torres
We prove the existence and multiplicity of periodic solutions of bouncing type for a second-order differential equation with a weak repulsive singularity. Such solutions can be cat…
Explicit solutions with non-trivial phase of the inhomogeneous coupled two-component NLS system
J. Belmonte-Beitia, F. Güngör, P. J. Torres
In this article, we construct novel explicit solutions for nonlinear Schrödinger systems with spatially inhomogeneous nonlinearity by means of the Lie symmetry method. We focus the…
Invariance of second order ordinary differential equations under two-dimensional affine subalgebras of EP Lie algebra
José F. Cariñena, Faruk Güngör, Pedro J. Torres
Using the only admissible rank-two realisations of the Lie algebra of the affine group in one dimension in terms of the Lie algebra of Lie symmetries of the Ermakov-Pinney (EP) equ…
